Definitions

  • the invention relates to a laser processing machine having a nozzle changing device.
  • JP 06 023580 A discloses a laser processing machine in which a nozzle changing device having a plurality of storage locations each for one laser nozzle is fitted to the upper side of a workpiece table facing a laser processing head. In order to avoid impeding the laser processing operation, the nozzle changing device is arranged outside the operating region of the laser processing head. In order to change a nozzle, either the laser processing head moves towards the nozzle changing device, or the nozzle changing device is moved towards the laser processing head by the workpiece table being moved.
  • EP 1 602 439 A2 discloses a nozzle changing device that is arranged, as part of a fitting station, beside a workpiece support or at the edge of a workpiece support. In both cases, the laser processing head of the machine travels a relatively long distance to a tool or nozzle changing position in order to change a nozzle.
  • a laser processing machine for processing workpieces includes a laser processing head having a nozzle receiving member configured to receive a laser nozzle; a workpiece support configured to hold workpieces on a workpiece support plane; and a nozzle changing device comprising a nozzle magazine having at least one nozzle storage location for a laser nozzle and being arranged at a side of the workpiece support plane that is remote from a side that faces the laser processing head.
  • the nozzle changing device is configured to assemble a laser nozzle on or to disassemble a laser nozzle from the nozzle receiving member of the laser processing head.
  • the workpiece support defines a through-opening through which a laser nozzle can be moved in a transverse direction to the workpiece support plane such that the laser nozzle is transferred between the nozzle magazine of the nozzle changing device and the nozzle receiving member of the laser processing head.
  • the nozzle changing device can include a handling device, by means of which a laser nozzle can be transferred between the nozzle magazine of the nozzle changing device and the nozzle receiving member of the laser processing head.
  • the workpiece support and the laser processing head can be configured to be moved relative to each other, and the nozzle changing device can be configured to be moved relative to the laser processing head into one or more of a changing position and a park position by means of a relative movement between the workpiece support and the laser processing head.
  • the workpiece support and the nozzle changing device can be configured to be jointly moved relative to the laser processing head such that the nozzle changing device can be moved into one or more of a changing position and a park position relative to the laser processing head by the movement of the workpiece support.
  • the nozzle changing device can be configured to be moved into one or more of a changing position and a park position by a support drive of the workpiece support, by means of which the workpiece support can be moved relative to the laser processing head together with a device for discharging products of the workpiece processing operation.
  • the nozzle changing device can be connected to the workpiece support.
  • the nozzle changing device can be configured to be moved relative to the workpiece support.
  • the nozzle changing device can include a handling device that is configured to transfer a laser nozzle in a transverse direction to the workpiece support plane between the nozzle magazine of the nozzle changing device and the nozzle receiving member of the laser processing head.
  • the handling device can be configured to transfer a laser nozzle through the workpiece support plane between the nozzle magazine of the nozzle changing device and the nozzle receiving member of the laser processing head.
  • workpieces are processed with a laser processing machine including a laser processing head having a nozzle receiving member configured to receive a laser nozzle.
  • the method includes holding a workpiece on a workpiece support plane of a workpiece support; transferring a laser nozzle between a nozzle magazine of a nozzle changing device located at a first side of the workpiece support and a nozzle receiving member of the laser processing head located at a second side of the workpiece support such that the laser nozzle is assembled on or disassembled from the nozzle receiving member; and moving the laser nozzle through a through-opening defined in the workpiece support along a transverse direction to the workpiece support.
  • the laser nozzle can be transferred between the nozzle magazine of the nozzle changing device and the nozzle receiving member of the laser processing head.
  • the workpiece support and the laser processing head can be moved relative to each other; and the nozzle changing device can be moved relative to the laser processing head into one or more of a changing position and a park position by means of a relative movement between the workpiece support and the laser processing head.
  • the workpiece support and the nozzle changing device can be jointly moved relative to the laser processing head such that the nozzle changing device is moved into one or more of a changing position and a park position relative to the laser processing head by the movement of the workpiece support.
  • the nozzle changing device can be moved into one or more of a changing position and a park position by a support drive of the workpiece support, by means of which the workpiece support can be moved relative to the laser processing head together with a device for discharging products of the workpiece processing operation.
  • the nozzle changing device can be connected to the workpiece support.
  • the nozzle changing device can be moved relative to the workpiece support.
  • the laser nozzle can be transferred along a transverse direction to the workpiece support plane between the nozzle magazine of the nozzle changing device and the nozzle receiving member of the laser processing head.
  • the laser nozzle can be transferred through the workpiece support plane between the nozzle magazine of the nozzle changing device and the nozzle receiving member of the laser processing head.
  • the nozzle changing device is more fully integrated into the laser processing machine.
  • the nozzle changing device is arranged at the lower side of the workpiece support plane defined by the workpiece support. Owing to this arrangement, the nozzle changing device does not produce a contour that interferes with normal machine operation, that is to say, during workpiece processing by means of the laser processing head. In this way, the nozzle changing device can permanently remain near the laser processing head.
  • the nozzle changing device is integrated in the functional center of the laser processing machine. If the laser processing head and the nozzle changing device have to carry out any relative movement in order to change a nozzle, only short paths have to be traveled. The nozzle changing device is further protected, at the lower side of the workpiece support plane, against damaging influences, for example, against contamination and undesirable mechanical loads.
  • the laser processing head Owing to the arrangement of the nozzle changing device below the workpiece support plane, particular measures are taken to produce the spatial proximity of the laser processing head and the nozzle changing device necessary for changing a nozzle. It is conceivable for the laser processing head to be movable, which allows the laser processing head and the nozzle changing device to be moved, simply by the laser processing head being moved, into a relative position in which it is possible to carry out a change of a nozzle.
  • the nozzle changing device can also include, in addition to a nozzle magazine, a handling device by means of which a laser nozzle can be transferred between the nozzle magazine of the nozzle changing device and the nozzle receiving member of the laser processing head and which laser nozzle can further also be assembled on or disassembled from the nozzle receiving member.
  • the nozzle changing device is arranged near the processing head when the changing position is taken up and is positioned farther away from the laser processing head in the park position. If the park position is taken up during normal machine operation, the nozzle changing device is substantially protected in the park position against damaging influences deriving from the processing operation, for example, against slag and material splashes when metal sheets are cut by laser.
  • a relative movement of the workpiece support and the laser processing head can be brought about in various manners.
  • the workpiece support can be moved relative to the laser processing head.
  • the nozzle changing device is connected to the workpiece support in terms of movement and can be moved into a changing position and/or into a park position by the workpiece support being moved.
  • a drive that is provided in any case for the workpiece support can also be used as a drive for the nozzle changing device.
  • the drive of the workpiece support that is used at the same time as the drive for the nozzle changing device can serve various purposes.
  • the laser processing machine can include a drive to be used to drive the nozzle changing device, which is otherwise used to move the workpiece support, together with a device for discharging products of the workpiece processing operation relative to the laser processing head.
  • a discharge device this may involve, for example, a flap that closes a discharge opening of the machine during the workpiece processing operation and that, in accordance with the size of the component to be discharged, is moved into various positions by the workpiece support being moved and associated movement relative to the laser processing head.
  • a connection between the nozzle changing device and the workpiece support in terms of movement is brought about particularly simply if the nozzle changing device is connected to the workpiece support.
  • the nozzle changing device can be moved relative to the workpiece support.
  • Such movability of the nozzle changing device is particularly advantageous when a relative movement of the workpiece support and the laser processing head is insufficient to transfer the nozzle changing device to a desired position, for example, to a changing position or a park position.
  • the positioning movement of the nozzle changing device is brought about partially by a relative movement of the workpiece support and the laser processing head and partially by a movement of the nozzle changing device relative to the workpiece support.
  • the part-movements can be superimposed on each other.
  • the handling device can be used.
  • the movement that is intended to be carried out by laser nozzles during the nozzle change in the transverse direction of the workpiece support plane can be brought about in various manners. Nozzle movement is conceivable using only the laser processing head, which in this case is to be lowered sufficiently far below the workpiece support plane. It is further possible to have a nozzle movement that is brought about partially by means of the handling device of the nozzle changing device and partially by means of the laser processing head. In the latter case, the laser processing head may also be to be lowered below the workpiece support plane.
  • the laser processing machine can include a handling device by means of which laser nozzles can be transferred through the workpiece support plane between the nozzle magazine of the nozzle changing device and the nozzle receiving member of the laser processing head. In this case, the nozzle changing operation does not require any movement, or at least only slight movement, of the laser processing head in the transverse direction of the workpiece support plane.

  • the laser nozzle 35 is carried in the direction of rotation by the nozzle holder 34 owing to corresponding shaping of the outer periphery of the laser nozzle 35 , on the one hand, and the inner periphery of the nozzle holder 34 , on the other hand.
  • the upwardly displaced nozzle holder 34 is lowered into its start position below the workpiece support 15 together with the laser nozzle 35 that has been taken up by it with corresponding actuation of the lifting device 41 ( FIG. 6 ).
  • the magazine turret 28 of the nozzle magazine 27 is unlocked in its direction of rotation and is again connected to the drive motor 29 of the nozzle changing device 26 .
  • the magazine turret 28 is then rotated about the turret rotation axis 30 by means of the drive motor 29 until another nozzle holder 34 (which, for example, can be directly adjacent to the nozzle holder 34 with the disassembled laser nozzle 35 in the direction of rotation) that has a new laser nozzle 35 is arranged below the through-opening 23 of the workpiece support 15 ( FIG. 7 ).
  • the lifting device 41 is actuated again. Consequently, the nozzle holder 34 moves upwards with the new laser nozzle 35 from its position according to FIG. 7 .
  • the laser nozzle 35 inside the nozzle holder 34 that has been moved upwards is positioned with the end of the threaded projection thereof located in the direction towards the laser cutting head 5 on the lower end of the nozzle receiving member 36 on the laser cutting head 5 .
  • the threaded projection of the laser nozzle 35 is resiliently supported in the direction of the shaft axis 38 on the edge of the nozzle receiving member 36 of the laser cutting head 5 .
  • the magazine turret 28 is again arrested in the direction of rotation and is disconnected from the drive motor 29 of the nozzle changing device 26 , and if the drive motor 29 is operated with a corresponding direction of rotation, the nozzle holder 34 that has been displaced upwards is rotated about the shaft axis 38 by means of its shaft 37 and by means of the planet wheel 39 thereof and the sun wheel 40 . As a result of that rotational movement, the threaded projection of the laser nozzle 35 that is applied to the laser cutting head 5 is screwed into the nozzle receiving member 36 .
  • the movement in an axial direction (that is, along the Z direction) that is intended to be carried out by the laser nozzle 35 during the screwing action into the nozzle receiving member 36 is brought about by the resilient force action of the laser nozzle 35 acting in that direction.
  • the laser nozzle 35 is fixed in the nozzle receiving member 36 of the laser cutting head 5 ( FIG. 8 ).
  • the drive motor 29 is stopped before the now-empty nozzle holder 34 is moved downwards by the lifting device 41 being actuated and, as a result, there is produced a situation that corresponds to the situation according to FIG. 4 .
  • the drive motor 29 of the nozzle changing device 26 is actuated and thereby the magazine turret 28 is moved about the turret rotation axis 30 into a rotation position, in which the dummy station 32 is again located below the through-opening 23 of the workpiece support 15 .
  • the workpiece support 15 moves in the direction of the double-headed arrow 14 (that is, along the Y direction) out of the position illustrated in FIG. 8 and into the position illustrated in FIG. 2 .
  • the trapdoor-like double flap 16 is closed by pivoting the frame-side leaf 44 and the support-side leaf 46 and the laser processing head is lifted in the direction of the Z axis into its start position.
  • the cutting station of the laser processing machine 1 is therefore again in the operational state provided for the processing operation for cutting the workpiece according to FIG. 2 .
  • the nozzle changing device 26 takes up its park position again with respect to the laser cutting head 5 .
  • FIGS. 9-15 can be provided in the laser processing machine 1 in place of the arrangement according to FIGS. 2-8 .
  • Corresponding reference numerals are associated with mutually corresponding components.
  • the trapdoor-like double flap 16 is movable in the opened state relative to the workpiece support 15 in a vertical direction (double-headed arrow 49 in FIGS. 2 and 9 , or the Z direction).
  • the support-side leaf 46 of the trapdoor-like double flap 16 (as indicated with dot-dash lines in FIG. 9 ) is further connected to the nozzle changing device 26 and, together therewith, can be moved relative to the workpiece support 15 in the direction of the double-headed arrow 14 (along the Y direction). Consequently, the workpiece support 15 can travel over the trapdoor-like double flap 16 and can thereby position the nozzle changing device 26 that is guided on the workpiece support 15 particularly far to the left towards the laser processing head 5 starting from the relationships according to FIG. 2 .
  • a vertical positioning drive 50 which is indicated in FIG. 9 , is used to adjust the height of the trapdoor-like double flap 16 .
  • the support-side leaf 46 of the trapdoor-like double flap 16 and the nozzle changing device 26 are moved relative to the workpiece support 15 in a horizontal direction (for example, the Y direction) by means of a horizontal positioning drive 51 , which is similarly indicated in FIG. 9 .
  • FIG. 9 shows the relationships during normal cutting operation.
  • the trapdoor-like double flap 16 is closed and is aligned at its upper side with the upper side of the workpiece support 15 .
  • the nozzle changing device 26 which is arranged below the workpiece support 15 , takes up its park position relative to the laser cutting head 5 and is in the operational state according to FIG. 10 . Accordingly, the nozzle changing device 26 is positioned relative to the workpiece support 15 in such a manner that the dummy station 32 of the nozzle magazine 27 is arranged so as to be displaced in the direction of the double-headed arrow 14 relative to the through-opening 23 of the workpiece support 15 .
  • the cross-section of the through-opening 23 in the workpiece support 15 and the cross-section of the through-channel 33 in the dummy station 32 partially overlap. Occurrences of contamination that occur during cutting operation, for example, slag or metal splashes, can pass through the through-opening 23 of the workpiece support 15 under the action of gravitational force and then either reach the upper side of a cover (not shown in detail) of the nozzle changing device 26 or directly pass through the through-channel 33 of the dummy station 32 downwards.
  • the trapdoor-like double flap 16 is opened and, in the opened state, is lowered below the workpiece support 15 by means of the vertical positioning drive 50 . Subsequently, the support-side leaf 46 of the trapdoor-like double flap 16 and the nozzle changing device 26 are moved together in a horizontal (Y) direction relative to the workpiece support 15 by means of the horizontal positioning drive 51 . The leaf 46 of the trapdoor-like double flap 16 and the nozzle changing device 26 are moved to the right relative to the workpiece support 15 out of the position according to FIG. 9 into the position according to FIG. 11 .
  • the dummy station 32 of the nozzle magazine 27 is located with its entire cross-section within the cross-section of the through-opening 23 in the workpiece support 15 . Occurrences of contamination that have previously become deposited on the upper side of the cover of the nozzle changing device 26 are brushed off the cover by the edge of the through-opening 23 in the workpiece support 15 during the movement carried out by the nozzle changing device 26 relative to the workpiece support 15 , and thereby reach the region of the opening of the through-channel 33 in the dummy station 32 .
  • the workpiece support 15 is moved to the left starting from the position according to FIG. 9 , together with the support-side leaf 46 of the trapdoor-like double flap 16 and the nozzle changing device 26 by means of the support drive 48 , until the through-opening 23 of the workpiece support 15 is located below the laser cutting head 5 and the nozzle changing device 26 takes up its changing position under the laser nozzle 35 that is intended to be disassembled.
  • the magazine turret 28 of the nozzle magazine 27 is rotated about the turret rotation axis 30 by the drive motor 29 until the empty nozzle holder 34 / 1 of the nozzle magazine 27 is arranged below the through-opening 23 of the workpiece support 15 .
  • the nozzle changing operation is carried out (as shown in FIGS. 12-15 ) as previously described with reference to FIGS. 4-8 .
  • the relationships according to FIG. 9 are reproduced by moving the workpiece support 15 relative to the laser cutting head 5 , moving the support-side leaf 46 of the trapdoor-like double flap 16 and the nozzle changing device 26 relative to the workpiece support 15 and by lifting and closing the trapdoor-like double flap 16 and lifting the laser cutting head 5 .
  • the laser cutting head 5 can be positioned in the direction of the double-headed arrow 14 with corresponding movability, and thereby take over a portion of the positioning movement necessary in this direction between the laser cutting head 5 and the nozzle changing device 26 .
